ENVELOP.

Specification of Letters Patent.

Patented Sept. 15, 1908.

Application filed April 30, 1908. Serial No. 430,12.

.To'alhwhom it may-concern.

I Be It known that I, FRANCIS V. DON- NELLY, a citizen of the UnitedStates of -America, residing at Greensburg, in the iounty ofWestmoreland and State of Pennsylvania, have invented certain new anduseghl Improvements in Envelops, of which the gillowmg is aspecification, reference being baa therein to the accompanying drawing.

1 Tina invention relates toenvelops, and the obyects of my inventionare, first, to provide simple and inexpensive envelop having a ositiveseal; second, to provide an envelop cannot be surreptitiously openedwithoutdetectlon; third, to provide a strong and durable enyelop thatcan be advantageously ex ress companies and parties trans- ;nittmg vauable matter through the mails;

2 'andfourth, to obviate the necessity of using an adhesive material forsealing an envelop.

I attain theabove objects by a construciiofi that will be presentlydescribed, and then specifically pointed out in the appended claims.

Referring to the drawing forming a part of this specification, Figure 1is a plan of apiece of paper from which my envelop is constructed, Fig.2 is a cross sectional view of the envelop in a closed or sealedposition,

Fig. 3 is a perspective view of the seal used in connection with theenvelop, Fig. 4 is a p anof the envelop with the end llaps and sealingflap thereof open, Fig. 5 is a plan withone of the end flapsfolded, Fig.6 is a 3 similar view with the sealing flap open, Fig. 7 ha similar viewof the sealing flap closed, Fig. 8 is a similar view illustrating theenvelop partially sealed, andFig. 9 is a similar view of the envelopsealed.

In the accompanying drawings, 1 desigmites the body of the envelophaving end 2 and 3, a bottom flap 4 and a sealing flap 5,- these flapsbeing to (led upon dotted lines 6.

(5 ,The bottom flap 4 is provided with ad hesive material 7 to bcsccurcdto the body 1 ofthe envelop, and it'isforiued with a tongue 8 adapted tobel'olded upon the dotted lines .9" and 10. The adhesive material 7 isem- 5 loyed simply to secure the lower edge of the ottom flap 4 to thebody of the envelop,

{whereby matter placed in the envelop cunliot extend to the lower edgeof said envelop, the object of which willpresently appear. After 5flisbottom flap 4 has been placed upon the fibdyl of the envelop, theend flaps 2 and 3 are folded inwardly upon the bottom nap 4, said endllaps being provided with slots 9 to dotted line 9, as illustrated inFigs. 5 and 6. The sealing flap 5 is adapted to be folded upon the endflaps 2 and 3, and is provided with a slot 11, to receive the tongue 8.The sealing flap 5 is formed with an auxiliary tongue 1 2 adapted to befolded upon the dotted line 1? said tongue lyingllush with the tongue 8,when-the same is bent downwardly, as best shown in Figs. 2 and S.

The tongues 8 and 12 are then bent to engage the front side of theenvelop, as shown in. Fig. 9 of the drawings, and a seal is employed forsecuring said tongues to the lower edge of the envelop. This sealcomprises an elliptical-shaped plate 14 having upwardly bent prongs 15.After the seal 18 placed in engagement with the lower edge of the on vclp, it is bent upon the dotted lines 16, whereby the prongs 15 willengage in the envelop and become clenched therein. It will be impossibleto remove the seal without ineasily detected.

By adhesively securing the bottom fiap to the body of the envelop, thematter carried within the envelop is prevented from being pierced by thelugs-15 of the seal.

I make my envelop of strong and durable paper or paperoid, and reservethe right to make the same of an desired size.

Having now descri ed my invention what I claim as new, is:-

1. An envelop comprising a body portion, end flaps, a bottom llapadapted to ave its lower edge adhesively secured to said body, a tonguecarried by said bottom flap, a sealing flap, and an auxiliary tonguecarried by said'sealing flap, said end flaps having slots formed thereinadapted to receive the tongue of said bottom flap, said scaling flaphaving a slot formed therein adapted to receive the tongue of saidbottom flap, said tongues being zid:ipted to be bent forward upon thelower front edge of said envelop, a plate i adapted to be bentinengagement with the E lower edge of said envelop, and prongs carricd-bysaid plate for engaging in said envelop, substantially as described.

2. An envelop com rising a body, a bottom fla ada )ted to old thereon, atongue carried iy sai bottomflap,end fla isada ted receive the tongue 8of the bottom flap 4. The tongue 8 is bent upwardly upon the juringtheenvelop, and such injury can be i to fold upon said bottom flap, sai endp6 having slots formed therein to receive the the lower edge of saidenvelop and pierce said 10 tongue of said bottom fiap, a sealin flaptongues.

adapted to fold upon said end flaps, $8.] sea In testimony whereof Iaffix my signature in' fia having a slot formed therein to re in thepresence of two witnesses.
